Abstract Aim Most vascular plants on E arth form mycorrhizae, a symbiotic relationship between and fungi. Despite the broad recognition of importance mycorrhizae for global carbon nutrient cycling, we do not know how soil climate variables relate to intensity colonization plant roots by mycorrhizal Here quantify patterns these relationships. Location Global. Methods Data root intensities two dominant types fungi world‐wide, arbuscular (4887 species in 233 sites) ectomycorrhizal (125 92...
ABSTRACT Two key plant adaptations for phosphorus (P) acquisition are carboxylate exudation into the rhizosphere and mycorrhizal symbioses. These target different soil P resources, presumably with carbon costs. We examined effect of inoculation arbuscular fungi (AMF) on amount carboxylates uptake 10 species low‐P adapted Kennedia grown 23 weeks in sand. Inoculation decreased some (up to 50%), dry weight (21%) increased content (23%). There was a positive logarithmic relationship between...
A decline in soil biodiversity is generally considered to be the reduction of forms life living soils, both terms quantity and variety. Where occurs, it can significantly affect soils’ ability function, respond perturbations recover from a disturbance. Several threats have been identified as having negative effects on biodiversity, including human intensive exploitation, land-use change organic matter decline. In this review we consider what mean by why important monitor. After thorough...
Abstract Soils have the potential to accumulate heavy metals and capacity do so is strongly related properties of each soil. Soil organic matter a key factor in retention, release, bioavailability metals, here we determined accumulation various types humus Rybnik Forest District southern Poland. In novel approach, analyzed relationships between within soil fractions evaluated role mediating metal mobility. Specifically, tested whether (i) type forest determines accumulation; (ii) associated...
Pastures often experience a pulse of phosphorus (P) when fertilized. We examined the role arbuscular mycorrhizal fungi (AMF) in uptake P from pulse. Five legumes (Kennedia prostrata, Cullen australasicum, Bituminaria bituminosa, Medicago sativa and Trifolium subterraneum) were grown moderate P, sterilized field soil, either with (+AMF) or without (-AMF) addition unsterilized soil. After 9-10 weeks, half pots received 15 mg kg(-1) One week later, we measured: shoot root dry weights;...
In the wider context of heathland restoration, we investigated how field scale experimental acidification with sulphur (sulfur) affected soil biodiversity, fertility and function over a period 17 years. A experiment was conducted in Isle Purbeck, England, using ferrous sulphate elemental as acidifying agents. We tested effects on fertility, plant communities, litter decomposition, microbiology (including fungi bacteria actinomycetes), arbuscular ericoid mycorrhizal colonisation, fauna...
Abstract In response to new European Union regulations, studies are underway mitigate accumulation of toxic cadmium (Cd) in cacao ( Theobroma , Tc). This study advances such research with Cd isotope analyses 19 genetically diverse clones and yeast transformed express natural resistance-associated macrophage protein (NRAMP5) heavy metal ATPases (HMAs). The plants were enriched light isotopes relative the hydroponic solution Δ 114/110 tot-sol = −0.22 ± 0.08‰. Leaves show a systematic...
It is known that roots can respond to patches of fertility; however, root proliferation often too slow exploit resources fully, and organic nutrient may be broken down leached, immobilized or chemically fixed before they are invaded by the system. The ability fungal hyphae resource far greater than due their innate physiological morphological plasticity, which allows comprehensive exploration rapid colonization in soils. symbionts ectomycorrhizal plants excrete significant quantities enzymes...
